Video does not redirect to external browser.

[Jawed]

Hi, I have created a chatbot with PVA in Teams. I have configured the bot to return a video using markdown code. When I am testing the bot, I am able to see the video thumbnail and when I click on the thumbnail, it redirects me to external browser to play the video. But once I publish the bot, the video link in the thumbnail is missing. When I click on the thumbnail, it only opens the image, but does not redirect me to the video.

Markdown code: [](http://www.youtube.com/watch?v=J90PUANbFQU "PVA")

The redirection link is available when testing the bot, if I click on the thumbnail it redirects me to the external browser to play the videoPublished bot. No redirection link. If i click on the thumbnail, it opens the image only, does not redirect me to the video.
